NENESUPPLY1st Generation 21mm Flange Insert Compatible with Elvie Flange Pump Parts Elvie Stride Flange Medela Momcozy Spectra Flange Willow Reduce 24mm to 21mm Use as Elvie Inserts Medela Insert

These work great and sit perfectly in the Lansinoh Discrete Duo. They wash great and are super soft

got these for my elvie stride i got. those came with 24mm size flanges. these were a great fit

Work great for adjusting flange sizes, comfortable, and easy to clean!

I use these with my Willow Go. Matches the Willow green pretty well. These inserts fit well and it is easy to remove to clean. No issues so far.

I ordered the 6pcs and only got 4 in my box. I like the product but I wish it was fully clear. I don’t know if I put the item on correctly to see if it’s centered for me. It does work with my spectra and baby buddah.

Definitely helps increase pumping output but inserts continue to fall out of the Medela 24 mm flanges which is annoying and likely losing some suction

Easy to use, good quality. They hold up in the dishwasher which is nice! I love that the green color matches my Elvie stride lol. Will definitely buy more if I need to resize

The media could not be loaded. One size does not fit most when it comes to pumping. I have an Elvie and Spectra and have been trying to find an insert that works in both flanges and the correct mm needed for a more comfortable pumping experience. I’m so happy I came across this product. The insert is very easy to insert on both my pump flanges, it’s pliable, and soft providing comfort. It doesn’t “stick” to the flange like other brands have and it does not require a lubricant to insert it into the flange.

It will probably get the job done with some pumps, but didn't work well with my Elvie pumps. It has to be adjusted and cut on some parts and still didn't pump too well.

Annoying they can’t go in the dishwasher
